I haven't used film for some years now but I found about seven films in the chest freezer, mix of 35mm and 120, guessing exposed between 2005 and 2008/9. Do you think these are still worth developing? - it would be nice to do that then sell my film developing kit (printing stuff went some yrs ago for comparatively speaking, not much money)I have some unopened chemicals I think bought about 2009/10 - can't see why stop bath and fix would go off, but unopened bottle of Paterson Aculux 3 after 2/3 years?
